What about Ultremos ZX 23 versus michelin Pro4 Comp Service course, or Pro4 Service course? Which ones are better and why?

I´m starting to hate my ultremos, as i've been using conti supersonic tubes of 50g, and a couple of times they scaped between rim and tired and exploded. Twice while inflating at home, one doing a rough sprint on a climb. I already switched to heavier tires to avoid this, but I'd like to return to 50g tubes with another tires, if that is possible. I think these new michelin would do the trick, but I'd like to have some confirmation.

Are these issues normal in Ultremos, as people already mentioned? will this happen also with 50g tubes and mich. pro4? thanks a lot.

After riding GP4000s for a couple of years, I tried Pro4's, loved the grip on dry surface, excellent descents,however got too many punctures, 5 in 2 months (always checked inside tyre, rim everything after a tube swap)had to go back to GP's as my teammates would start hating me for the delays on rides...

Would definitely go to Pro4's again in certain conditions, but they are certainly not an all rounder (which they were not designed to be anyway)

The puncture thing is what has me hesitant to switch away from the GP4K - which version of the Pro4 did you try? Was it the regular Service Course, or one of the lighter ones?

Using Pro 4 endurance (Irish roads + fat git) so far they have been excellent. I have used Michelin tyres for years and have to say I think Pro 3 were a step backwards, these put Michelin back on top imho.
